The Heat developers are pleased to announce the release of the Heat API

version 4.  We have added many new features including Ubuntu Precise
host support.

Heat is a project designed to work with OpenStack that provides a
programmable interface to orchestrate multiple cloud applications
implementing CloudFormation.

To give it a spin on Fedora 17:

Or on Ubuntu 12.04:

Enhancements in version 4:

+ Cloud Watch.
  cfn-push-stats can be used on the guest to send statistics to the heat
  metadata server which can use rules defined in the template to
  execute actions.

+ High Availability using CloudWatch
  - cfn-hup has been modified to be able to check and restart services
    (any other monitoring tool could also be used).
  - cfn-push-stats is used to send a service-failure event to CloudWatch.
  - Service escalation can be achieved by using the Restarter Resource
    as an action.

+ Authentication and identification.
  Heat now performs proper authentication on all API calls, identifying
  individual users, and creating stacks on a per-user basis.  Heat now
  also supports AWS style keys as well as keystone username/password or
  token authentication.

+ Nested stack support.
  Heat templates can now reference other templates enabling you to use
  them as building blocks to create larger deployments.

+ API rework to align with AWS.
  This is part of an ongoing effort to conform to Amazons API and to
  move towards using boto as our client.
